In addition, the system label list 33 may additionally include the project name of the project, but the project name is not a mandatory item of the system label list 33. [

In the system label list 33, each of the plurality of rows 33a corresponds to each byte of the link device in which the control device 2 writes data. The system label list creation section 14 creates system labels, which are identifiers that uniquely specify each link device, in the system label item in each of the plurality of rows 33a in accordance with a predetermined generation rule .

In the first embodiment, the predetermined generation rule includes a character string "start ", a station number of the control device that writes data to the link device, a character string" switch of station " Is a rule that combines the serial numbers of the link devices that write the link device.

In the system label list 33, the system label list of the first row of the plurality of rows 33a includes the " switch 1 of the start_1 station " generated by the system label list creation unit 14. [ In addition, in the item of the system label in the last row of the plurality of rows 33a, the " switch 1 of the start_1 station " generated by the system label list creating section 14 is arranged.

In addition, the system label list creation section 14 arranges the CPU name " CPU01 " embedded in the control device 2 in the item of the CPU name in each of the plurality of rows 33a. In addition, the system label list creation unit 14 places, in each of the plurality of rows 33a, a device name that uniquely identifies each link device in the device name field.

In the system label list 33, each of the plurality of rows 33b corresponds to each byte of the link device from which the control device 3 writes data. The system label list creation unit 14 creates system labels, which are identifiers uniquely identifying each link device, in the system label items in accordance with a predetermined generation rule in each of the plurality of rows 33b, do.

In the system label list 33, the system label list of the first row of the plurality of rows 33b includes the " switch 1 of the start_2 station " generated by the system label list creation unit 14. [ In addition, in the item of the system label in the last row of the plurality of rows 33b, the "switch 16 of the start_2 station" generated by the system label list creating unit 14 is arranged.

In addition, the system label list creation unit 14 arranges the CPU name "CPU02" embedded in the control device 3 in the item of the CPU name in each of the plurality of rows 33b. In addition, the system label list creation unit 14 places, in each of the plurality of rows 33b, a device name that uniquely identifies each link device in the device name field.

In addition, the system label list creation unit 14 places, in each of the plurality of rows 33c, a device name that uniquely identifies each link device in the device name field.

As described above, according to the system design support tool 6, the system label list creating unit 14 stores the system configuration diagram 30, the network range allocation information 32, and the projects 31a, 31b, and 31c The system label list 33 can be created. This makes it unnecessary for the operator to input each item of the system label list 33, so that occurrence of an input mistake in the system label list 33 can be suppressed. Therefore, the system design support tool 6 can suppress the possibility that the control program will perform an unexpected operation, and it is possible to suppress the possibility that the controlled device will perform an unexpected operation.

In addition, the system design support tool 6 is highly suitable to protect the system label list 33 so that the operator can not change the system label list 33 to a tabular calculation program or a text editor. As a result, the operator can not change each item of the system label list 33, so that it is possible to suppress the occurrence of a change miss in the system label list 33. Therefore, the system design support tool 6 can suppress the possibility that the control program will perform an unexpected operation, and it is possible to suppress the possibility that the controlled device will perform an unexpected operation.

8 is a flowchart showing a system label change operation of the system design support tool according to the first embodiment. Here, the case where the control device 4 having the station number "3" is replaced with a new control device having the station number "4" will be described as an example.

First, in step S110, the system configuration diagram creating unit 10 changes the system configuration diagram 30. FIG. Specifically, the system diagram generation section 10 corresponds to an object 30c corresponding to the control apparatus 4 having the station number "3" as shown in FIG. 4, corresponding to the new control apparatus having the station number "4" (30h).

9 is a diagram showing a system configuration diagram according to the first embodiment. The system configuration diagram 30 is obtained by replacing the object 30c corresponding to the control device 4 having the station number "3" with the object 30h corresponding to the new control device having the station number "4".

Referring back to Fig. 8, in step S112, the project assignment unit 12 changes the assignment of the project 31c to the object 30h.

10 is a diagram showing a system configuration diagram according to the first embodiment. The project assigning unit 12 assigns the object 30g to the object 30h corresponding to the new control apparatus with the station number "4", based on the operator's operation input. The object 30g corresponds to the project 31c.

Referring again to FIG. 8, in step S114, the network range assignment information creating section 13 changes the network range assignment information.

11 is a diagram showing network range assignment information according to the first embodiment. The operator inputs an entry for changing the station number in the third row 32c of the network range assignment information 32 from "3" to "4".

Referring again to FIG. 8, in step S116, the network range assignment information duplication determination unit 15 performs duplication check of the network range assignment information 32. [ More specifically, the network range assignment information duplication determination unit 15 checks whether or not the address range of each row of the network range assignment information 32 is duplicated.

Next, in step S118, the first system label list changing section 16 collates the system configuration diagram 30, the network range assignment information 32, and the projects 31a, 31b, and 31c with the station number as a key, The system label list 33 is changed.

12 is a diagram showing a system label list according to the first embodiment. In the system label list 33 shown in Fig. 12, a plurality of rows 33d are changed, and a plurality of other rows are not changed.

Each of the plurality of rows 33d of the system label list 33 corresponds to each byte of the link device in which the new control device with the station number "4" writes data. The first system label list changing section 16 creates a system label as an identifier for uniquely specifying each link device in the system label item in each of the plurality of rows 33d in accordance with a predetermined generation rule, .

In the system label list 33, the " switch 1 of the start_4 station " generated by the first system label list changing section 16 is placed in the item of the system label in the first row of the plurality of rows 33d have. In addition, in the item of the system label of the last row of the plurality of rows 33d, the "switch 16 of the start_4 station" generated by the first system label list changing section 16 is disposed.

In addition, the first system label list changing section 16 sets the CPU name " CPU04 " embedded in the new control apparatus having the station number " 4 " do.

As described above, according to the system design support tool 6, the first system label list changing section 16 changes the system configuration diagram 30, the network range allocation information 32, and the projects 31a, 31b, and 31c to the station number The system label list 33 can be changed. This makes it unnecessary for the operator to change each item of the system label list 33, so that it is possible to suppress the occurrence of a change mistake in the system label list 33. [ Therefore, the system design support tool 6 can suppress the possibility that the control program will perform an unexpected operation, and it is possible to suppress the possibility that the controlled device will perform an unexpected operation.

In addition, the system design support tool 6 is highly suitable for protecting the system label list 33 so that the operator can not change the system label list 33 to a table calculation program or a text editor. As a result, the operator can not change each item of the system label list 33, so that it is possible to suppress the occurrence of a change miss in the system label list 33. Therefore, the system design support tool 6 can suppress the possibility that the control program will perform an unexpected operation, and it is possible to suppress the possibility that the controlled device will perform an unexpected operation.

In the above example, the flowchart of FIG. 8 has been described by taking as an example a case where the control apparatus 4 having the station number "3" is replaced with a new control apparatus having the station number "4". Next, For example, the flowchart of FIG. 8 will be described.

In the case where the link device has increased or decreased, there is no change in the system configuration.
